Iowa) Etiologic Risk Group (see link below):Appendix B-III-A. Risk Group 3 (RG3) - Bacterial Agents Including Rickettsia */Disease Information (sort of like the Intro to your Mini Research Write up): R. rickettsia is a unicellular, Gram-negative coccobacillus that is native to the Americas. It is known to cause Rocky Mountain Spotted Fever (RMSF), a disease that can be lethal if not treated. RMSF symptoms include fever, headache, pain, and a rash. R. rickettsii is spread by Dermacentor Ticks. Even when treated with current antibiotics, some patients can require hospitalization because R. rickettsii infects the lining of the blood vessels, which may damage the respiratory system, the central nervous system, gastrointestinal system, or kidneys. If the infection is severe enough there is a chance for partial paralysis of the lower extremities, gangrene (may require amputation), and loss of hearing and bladder control. Research of R. rickettsii started when early settles of Western Montana began to be plagued with a disease that they called “black measles” because of its severe dark rash. Fatalities occurred in nearly 4 out of 5 adult cases. This caused the Montana State Board of Health to bring in scientists to investigate the cause and treatment for the spotted fever. One such scientist was Dr. Howard Ricketts, a pathologist, who in 1906 had discovered that the vector for the disease was the Rocky Mountain wood tick. Then in 1909 he had isolated the bacterium that was responsible for the disease, which was later named Rickettsia rickettsii in his honor. This spawned the building of The Rocky Mountain Labs, one of the few Biosafety level 4 laboratories. http://www.niaid.nih.gov/about/organization/dir/rml/pages/history.aspx
Essentiality of this protein: Acetlyglutamate kinase catalyzes the second and frequently controlling step of arginine synthesis which is key for meaning cellular functions.
